DTC C1436: Yaw Rate Sensor Malfunction: Procedure

1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG).
3. Select the Data List on the Techstream. Refer to DATA LIST / ACTIVE TEST .
   ABS/VSC/TRAC
   
   

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   Yaw Rate Sensor	Yaw rate sensor / min.: -128 deg/s, max.: 127 deg/s	Vehicle stationary: 0 deg/s Right turn: -128 to 0 deg/s Left turn: 0 to 127 deg/s	-
   Yaw Rate Sensor2	Yaw rate sensor 2 / min.: -128 deg/s, max.: 127 deg/s	Vehicle stationary: 0 deg/s Right turn: -128 to 0 deg/s Left turn: 0 to 127 deg/s	-

4. Check that the yaw rate and acceleration sensor output value displayed on the Techstream.

   Result

   Result	Proceed to
   NG (The yaw rate and acceleration sensor output value is 0 deg/s when the vehicle is stationary, but the value fluctuates when turning)	A
   NG (The yaw rate and acceleration sensor output value is not 0 deg/s when the vehicle is stationary)	B
   OK	C

   NOTE:

   Check the yaw rate and acceleration sensor signal after replacement. Refer to TEST MODE PROCEDURE .

   HINT: 

   If troubleshooting has been carried out according to Problem Symptoms Table, refer back to the table and proceed to the next step. Refer to PROBLEM SYMPTOMS TABLE .

B → See step   3 

C → See step   5 

A: Go to next step 

1. Turn the engine switch off.
2. Check that the yaw rate and acceleration sensor has been installed properly. Refer to INSTALLATION .

   OK

   The sensor should be tightened to the specified torque.

   The sensor should not be installed in a tilted position.

   NOTE:

   Check the yaw rate and acceleration sensor signal after replacement. Refer to TEST MODE PROCEDURE .

   HINT: 

   If troubleshooting has been carried out according to Problem Symptoms Table, refer back to the table and proceed to the next step. Refer to PROBLEM SYMPTOMS TABLE .
